From b1bc4973177035bce5a5e0483abbbe12e6f9005b Mon Sep 17 00:00:00 2001 From: John Garry Date: Tue, 15 Aug 2023 11:51:47 +0000 Subject: [PATCH 01/10] scsi: libsas: Delete sas_ha_struct.lldd_module Since libsas was introduced in commit 2908d778ab3e ("[SCSI] aic94xx: new driver"), sas_ha_struct.lldd_module has only ever been set, so remove it. Struct scsi_host_template already has a reference to the LLD driver module as to stop the driver being removed unexpectedly.
